Application filed April 2, 1915. Serial No. 18,725.

To all whom it may concern Be it known that I, Hona'rro Gr. GILLMoR, acitizen of the United States. and resident of Washington, in theDistrict of Columbia, have invented a new. and useful Improvement inRail-Anchors, of which the following is a specification, accompanied bydrawings.

This invention relates to devices known as rail anchors, rail stays oranticreepers and one of its objects is to form a simple device whichwill prevent longitudinal movement of the rails of railways.

Another object of the invention is-to provide means for securing thedevice upon the rail in such manner he lost by a reverse movement of therail or by the vibrations to which the rail is subject.

0 the accomplishment of these objects and such others as may hereinafterappear, as will be readily understood by those the invention comprises arail anchor, embodying features of construction, the combination ofelements and arrangement of parts having the general mode of operationas hereinafter described and claimed.

The preferred embodiment of the invention is shown in the accompanyingdrawings, in which Figures 1, 2 and 3 are, respectively, a plan view, aside elevation and a transverse elevation showing the device inoperative position on the rail. Figs. l and 5 are, respectively, a planviewand a transverse elevation showing two positions of the device whilebeing placed upon the rail. Fig. 6 is a section through the rail and thedevice at the plane indicated by the line X X in Fig. 1.-

Similar letters apply to similar parts throughout the several views.

In the embodiment of the invention illustrated in the drawings A is therail and B the rail anchor, constructed with a tie abutting portion 0which engages with a face of the tie D. The anchor B is constructed withshoulders E and F arranged to engage the edges of the rail base flangeand a jaw G formed by the projecting rib H. For additional strength tothe shoulder F and the jaw G the web I is provided. The opposite end ofthe anchor B is formed with an arm K arranged to engage the upperSpecification of Letters Patent.

surface of the rail base flange above the tie when the tie abuttingportion of the anchor C is engaging the vertical face of the tie asshown in the Figs. 1, 2 and 3. To give stiffness to this arm K the ribsor flanges L and M are provided. The tie abutting portion C is providedwith a stiffening web N and the shoulder E is strengthened bv the web orflange O. U

To place the device in position on the rail it is brought below the railwith the arm K just engaging the top of the rail base flange and movedto such an angle that the end of the rib H, forming the jaw G, can

be raised by the edge of the rail base flange that its hold shall not atthe side of the rail opposite to the arm K. This position is illustratedin Fig. i. In this position the shoulder E is below the rail base flangeas shown. The device is now moved transverse to the rail and at the sametime moved angularly in relation to the rail-until the jaw G has theedge of the rail base flange entered as shown in Fig. 5. In thisposition the shoulder E is still below the rail bottom and the body ofthe device B is subject to some torsion. If the device he now.forced toposition by further rota tion of B in relation to forcing the rail edgeinto the jaw G, which necessary movements may be produced by tapping Itransversely in refation to the rail and O longitudinally of the railthe position shown in Fig. 1 will be reached and in this position theface of the shoulder E will clear the edge of the rail base flange andthe torsion of the body of B will cause this shoul der to engage theface of the shoulder E with the edge of the rail base flange. When thedevice B is in this position the opposite edges of the rail base flangeare engaged by the-shoulders E and F as shown in the section Fig. 6.

The direction in which the rail tends to move is indicated by the arrowin Fig. 1. This movement will be referred to as the forward movement ofthe rail. 'As the rail moves forward it carries with it the device Buntil the tie abutting portion 0 comes into contact with the tie D.Thefirst effect ofany further tendency of the rail to move forward is toimpart a torsional movement to B the arm K of which is engaging theupper surface of the rail base flange forwardof the tie abutting portionC, so that if the shoulder E is not already in full en- 'the rail andby' tion may be embodied having integral rail gagement with the edge ofthe rail base flange the torsional movement of B produced by thisforward movement of the rail with C in contact with the tie D willcomplete the engagement of the shoulder E with the edge of the rail baseflange.

The rail base flange at the side opposite to C and K is gripped in thejaw G and any further tendency to forward movement of the rail willcarry forward, with the rail A, the jaw G altering slightly the angle ofB to the rail A. This angular movement of B in relation to A will causethe rail edges to be more firmly gripped between the shoulders E and Fand thus automatically increase the resistance which the device opposesto further movement of the rail.

Should the rail, through change in temperature'. or other cause, move inthe backward or reverse direction the device B will be carried with therail in this reverse direction and thestress on the forward face of Cwould be released. It will .be readily understood that even when this isthe case, the engagement of the shoulders E and F with the base flangeedges will prevent the vibration of the rail from loosening ordisengaging the device upon the rail. Moreover, should C be held againstthis backward or reverse movement the jaw G would be carried backward bythe rail and B moved angularly upon the rail. The effect of this angularmovement would be to tighten the device and further prevent its beingdetached from the rail.

Obviously some features of the invention may be used without others andthe invenin widely Varying forms within the scopeof the artisan.

Therefore without limiting the invention to the construction shown anddescribed or enumerating equivalents, I claim and desire to secure byLetters Patent 1.
